html Video tag not working in ios with blazor wasm app

I’ve a html video that I need to play on the homepage, that is copied from the dev instruments on a (working) chrome browser.

<div class="VidContainer" b-if4auixgu9="">
   <video autoplay="" muted="" loop="" playsinline="" b-if4auixgu9="">
      <supply src="https://rafflegames.blob.core.home windows.internet/publicvideos/BeAWinner.mp4" sort="video/mp4" b-if4auixgu9="">
    Your browser doesn't assist the video tag.
   </video>
</div>

It additionally works on a Mac utilizing Chrome however not Safari, so I suppose that is some form of Apple foible.

I did see this query right here: MP4 Movies on web site embed with html5 doesn’t play on iOS … however I do not actually perceive easy methods to create the intermediate certificates, so I’ve tried additionally transferring the ‘supply’ to be native to the server so it is not going externally for it. That didnt clear up it.

I simply need it to play good prefer it does on every little thing else. Any ideas? Is that this a Blazor WASM particular factor or is Safari only a bit damaged/awkward?
